Foldable Electronic Device Hinge Mechanism for Flexible Display Wrinkle Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices face challenges in adapting to shape and size changes during extension and folding, leading to issues like bulging, wrinkling, and separation due to existing mechanism designs that fail to accommodate flexibility effectively.
Innovation Solution
An electronic device design featuring a first and second body connected by a rotating shaft, with a driving member and a third body that moves along a path to adjust the flexible display's position, allowing smooth switching between folded and unfolded states, thereby avoiding size differences and preventing wrinkling or separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display device uses a traditional fixed mechanism design, then the device structure is simple, but the flexible display panel cannot accommodate shape and size changes during extension and folding, causing bulging, wrinkling, and separation
Solution Approach 1:
The patent applies dynamics by making the third body movable relative to the second body through a driving member. This allows the mechanism to dynamically adjust its configuration based on the flexible display's state (folded or unfolded), enabling adaptation to shape and size changes while maintaining structural integrity and preventing display panel deformation.
2Area of moving object
If the flexible display panel is extended for large area display, then the display area increases, but the device mechanism cannot accommodate the shape changes, causing the display panel to deviate from its original position
Solution Approach 1:
The driving member enables the third body to move dynamically, allowing the mechanism to accommodate the shape changes that occur when the flexible display is extended. This dynamic adjustment prevents the display panel from deviating from its original position while maintaining the ability to achieve large display areas.
3Ease of operation
If the device is folded for convenient carrying, then the portability improves, but the fixed mechanism causes size differences in the flexible display, leading to wrinkling and separation
Solution Approach 1:
The movable third body driven by the driving member allows the mechanism to dynamically adapt to the folded state. This prevents size differences in the flexible display during folding, thereby avoiding wrinkling and separation while maintaining display integrity and reliability during portable carrying.
4Device complexity
If a traditional fixed mechanism is used, then the device structure is simple, but it cannot accommodate the flexibility of the display, causing bulging and separation
Solution Approach 1:
The patent introduces a movable third body that can dynamically adjust its position relative to the second body. This dynamic capability allows the mechanism to accommodate the flexibility of the display panel, preventing bulging and separation while maintaining structural integrity without excessive complexity.

AI summary
An electronic device includes a first body, a second body, a rotating shaft connected with the first body and the second body, at least one driving member, a third body and a flexible display. The first body and the second body rotate relatively to be folded or unfolded via the rotating shaft. The driving member is movably pivoted to the rotating shaft. The third body is movably disposed at the second body, the third body is located on a moving path of the driving member, and the third body and the driving member rotate relative to the first body to be folded or unfolded along with the second body. The flexible display is disposed at the first body and the third body, and the driving member drives the third body to move close to or away from the first body in a rotating folding or unfolding process.
